Summary

Summary: Loki’s idea of an – unintentional yet effectively hilarious – practical joke is to turn Tony into a 5-year-old. The remaining Avengers soon realize they may not be able to handle the boy-genius. While Thor hunts his brother down in order to turn Tony back to his older self, the rest of the team seeks help from a man who, in the past, was more of a father figure to Tony than Howard Stark himself: Edwin Jarvis.
